semai Flange Inserts 21mm Breast Pump Parts Compatible with Medela/Momcozy S12 Pro/S9 Pro/S12/S9/Spectra/Elvie 24mm Breast Pump Shields/Flanges, Reduce 24mm Nipple Tunnel Down to Correct Size, 4PCS

Must have if your pumping I get so much more milk with these

Good selection of sizes easy to use.. Note only 1 of each size in pack

Got these for my momcozy pro pump and they fit great. I had originally bought a single flange but i changed shape and needed a different size so this has been great as it comes with multiple sizes.

Much easier and cheaper than buying different flanges, crazy that most breast pumps only provide 24mm/21mm sizes. Works well in Medela breast pump.

These are good. I should have measure first and bought two rather than box of all, but then it's good if they change over time, which funnily mine have.

I was looking for a flange insert for my 24mm Spectra Handsfree Shield Cups. It was a comfortable fit and helped me maintain my supply. All in all, a good product in budget.

The don’t fit the medala pump as advertised

Great product, helped find the perfect size flange for me.

These flange inserts saved my poor areolas from using flanges that were too big! Contrary to what we’ve all been told, size 24 flanges DO NOT fit a lot of us. I was measured by a lactation consultant for flange size when my son was in the NICU, and was told I was between a 21 and a 24….. NOPE! I had a really hard start to breastfeeding and did a lot of pumping and had really sore and bruised areolas from using flanges that were too big. When I decided to measure myself again, I realized I was a 17!! Since using these inserts, pumping hasn’t been so uncomfortable and my areolas aren’t bruised! What I like about this company too, is they offer a sample pack of different sizes to try so you find the perfect fit, which I think is amazing, since your flange size can change throughout your pumping journey, as well as be different from left to right! They are soft and comfortable, easy to use and easy to clean! So thankful for these things!!

They were good but I needed pairs for inserts.

Got the multiply pack to check my size and then bought more of the right size! Need a flange size 28mm and insert of 17mm even tho I was told it wouldn’t rfit it does and amazing has helped my supple so much!

Oh my goodness this is a game changer! I had a lactation consultant size me at the hospital for the correct flange and got the breast pump from them with the flanges that fit. However, after the first two weeks of breastfeeding and using a breast pump, nipples stop being so engorged, so suddenly my flanges were too large and my breasts hurt so bad after pumping. My lactation consultant remeasured me and recommended these inserts instead of paying a ton to replace flanges. Big money saver, super easy to use and clean. To get them into the flange, I just pinched the opening closed and it slides into the flange easily. You can push or pull on it gently to adjust it just fine. I like that these can be used with my at home pump, and also work for my travel pump. Definitely recommend.

There is five different sizes in this package. Not two of each. I did have a hiccup with my order and had a few missing however upon contacting Amazon I got the issue resolved overall super happy.
